The STM32F746NGH7 is a 32-bit ARM Cortex-M7 single-core MCU from STMicroelectronics' STM32F7 series, clocked at 216 MHz. That clock rate, combined with the single-precision FPU and DSP instructions, gives it enough headroom for real-time control loops, audio processing, or driving a TFT display through the built-in LCD parallel interface. The 1 MB Flash and 320 KB RAM support moderately complex firmware stacks — think Ethernet + USB host + a GUI library — without external memory for most applications. The 168 GPIOs and peripherals — CANbus, Ethernet, USB OTG, SPI, I²C, UART, SPDIF-Rx — suit industrial gateways and motor-drive control boards.

Product details
Frequently asked questions
What is the pinout of STM32F746NGH7?
The pinout is defined in the STM32F746NGH7 datasheet for the 216-TFBGA package. The 168 I/O include multiple alternate functions mapped to specific ball positions.
What is the difference between STM32F746NG and STM32F745?
The STM32F746NGH7 runs at 216 MHz and includes a Chrom-ART graphics accelerator and LCD-TFT controller, while the STM32F745 tops out at 216 MHz as well but lacks the dedicated graphics hardware. Both share the same Cortex-M7 core and 1 MB Flash option, but the F746 is the display-oriented variant.
